CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 285,228, datedSeptember 18, '1883.

' I Application iiled June 1S, 1883. (No model.)

.To LEZ whom it may concern:

Be it known that I, J osIAII P. CHAMPION, residing at Phelps, in thecounty of Ontario and State of New York, have invented an ImprovedAutomatic Gar-Coupling, of which the following is a specification.

Referring to the drawings accompanying this 'speciiicatiom Figure lrepresents a side View of my invention; Fig. 2, a top View, and Fig. 3 aseparate top View of the slide C.

The same letters of reference refer to like parts.

slide.

J is a four-armed cam-Wheel turning on a pivot through a slot in thebuffer.

K is a gate working perpendicularly, formed of the cross-piece L andupright bars, working freely through holes in the buffer. Rigidlyattached to the cross-piece L is an arm, M, sup

porting looselythe pin N, which engages with the link.

The operation of the invention is as follows: When the ears are to becoupled, the link O enters the buffer A. At the same time the projectingslide C is pushed in by the buffer B the front end of the dog E pushesagainst one of thearmsof the cam-wheel J, followed by the shoulder Iagainst another arm, partly turning the wheel. Another arm engages withthe erossvpiece L of the gate, raising the same, and, by means of thearm M, the pin N, to permit the passage of the link under the pin. Acontinuation of the same motions disengages the arm of the cam-wheelfrom the-oross-piece L, when the gate and pin immediately fall, the

latter passing through the link and its lowerl end through a slot in theslide G and a hole in the under side of the buffer, thus securelycoupling the cars together.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

I. In an automatic car-coupling, the slide C, constructed with the dogE, spring I-I, and shoulder I, operating in combination with thefour-armed cam-wheel J andspring D, or its equivalent, substantially asdescribed.

2. In an automatic car-coupling, the fourarined cam-wheel J, incombination with the gate K, with its arm M, operating the pin N,substantially as described.

8. In an automatic car-coupling, the eombination of the slide C,constructed as described, spring I), or its equivalent, four-armedcamwheel J, and gate K, with its arm M, operating the pin N,substantially as and for the purposes herein set forth and described.
